  1. 1. Evaluating the Performance of Propulsion System Elements in an Aerospace Company

    University essay from KTH/Kraft- och värmeteknologi

    Author : David Fredouelle; [2023]
    Keywords : Turbomachinery; injector; test campaign; cryogenic; rocket engine; test bench; cold flow; Turbomaskin; injektor; testkampanj; kryogen; raketmotor; testbänk; kallt flöde;

    Abstract : This paper examines two examples of testing activities of sub-components of a 300kN methalox first-stage rocket engine developed by Pangea Aerospace, namely, theinjectors and the cryogenic pumps. One of the difficulties of these test campaignsis to evaluate the performances of these sub-components without using cryogenicpropellants and in conditions differing from flight conditions.

  3. 2. Development and characterization of multi-streams heat exchangers for liquefaction cycle analysis in the contextof hydrogen mobility

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : WULLSCHLEGER LÉA; [2023]
    Keywords : Liquefaction cycle; multi-streams heat exchanger; Matlab; PROOSIS; AMESIM; ArianeGroup;

    Abstract : This paper presents the master thesis work done at ArianeGroup on the development and characterization of multi-streams heat exchangers for liquefaction cycle analysis in the context of hydrogen mobility. In 2015, the Paris Agreements aimed at strengthening the global response to the threat of climate change by keeping the temperature rise below 1. READ MORE

  4. 3. Superconducting gates for InP HEMTs

    University essay from KTH/Tillämpad fysik

    Author : Sebastian Alveteg; [2023]
    Keywords : Cryogenic electronics; HEMT; Superconductors; Applied Physics; Kryogenisk elektronik; HEMT; Supraledare; Tillämpad fysik;

    Abstract : The thesis examines the prospects of using the superconductor NbN as the gatemetal for an InP HEMT. A HEMT or High Electron Mobility Transistor is aheterostructure transistor engineered to reach very high electron mobility. InPHEMTs are used as cryogenic Low Noise Amplifiers (LNAs), which have increasedin demand as quantum computing is scaling up. READ MORE

  5. 4. Transportation of hydrogen : A comprehensive analysis of the cost of different methods of transportation of hydrogen

    University essay from KTH/Materialvetenskap

    Author : Stina Gardesten; Julius Modin; [2023]
    Keywords : Hydrogen; Energy transportation; pipeline; gas tube; gas tank; Morocco; Väte; energitransport; pipeline; gastub; gastank; Marocko;

    Abstract : Today, the world faces an energy source transformation that is difficult to grasp. To convert to a green energy society, carbon, oil, and natural gas must faze out as fuels during the upcoming decades. READ MORE

  6. 5. Cryo-CMOS ICs for Scalable Superconducting Nanowire Single Photon Detectors

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)
